Puzaku

Word Logic · Brain Training — Free browser puzzle

What is Puzaku?

Puzaku is a free word logic puzzle that you can play directly in your browser — no download, no registration, no app required. It combines the logical deduction of grid-based puzzles with the vocabulary challenge of anagrams, creating a unique two-phase brain training experience that tests both your reasoning and your word skills in a single timed session.

Every puzzle starts with a partially filled letter grid. Your goal is to complete the grid so that every row, every column, and every box contains each letter of a hidden word exactly once — the same logical rules you would find in a number-placement puzzle, but with letters instead of digits. Once the grid is complete, the game reveals the letters as a scrambled anagram, and you race to unscramble them and spell out the hidden word before the clock stops.

Puzaku is designed for short, focused sessions that sharpen your mind. A single puzzle takes anywhere from one to five minutes depending on your chosen grid size and difficulty. The combination of spatial logic, pattern recognition, and vocabulary recall makes it an effective daily brain training exercise that feels more like a game than a workout.

How to Play

Phase 1 — Fill the Grid: You are presented with a letter grid that has some cells pre-filled. Your task is to place the remaining letters so that every row, every column, and every box contains each letter of the hidden word exactly once. Tap an empty cell to select it, then choose a letter from the palette. The timer starts when the puzzle opens. If you get stuck, hints are available — though they come with a time penalty that increases based on how many you have used.

Phase 2 — Crack the Anagram: Once the grid is complete, the letters of the hidden word appear in a scrambled order. Tap them in the correct sequence to spell the word. The timer keeps running from the grid phase, so your final time reflects how quickly you solved both challenges. If you recognise the word immediately, this phase takes just a few seconds — but trickier words can add valuable time to your score.

Beat Your Best Time: Every puzzle is timed. Your daily results are kept so you can see your streak and best times, and practice levels record your personal best. Share your daily result as a spoiler-free emoji grid.

Three Grid Sizes, Three Difficulty Levels

Puzaku offers nine different combinations of grid size and difficulty to suit every skill level. The 4×4 Novice grid uses four-letter words and is perfect for beginners or for a quick warm-up. The 6×6 Classic grid uses six-letter words and provides the core Puzaku experience — challenging enough to require real deduction, fast enough to fit in a coffee break. The 9×9 Master grid uses nine-letter words and demands serious concentration, with larger boxes and more complex letter interactions.

Each grid size can be played on Easy, Medium, or Hard difficulty. The difficulty setting controls how many letters are pre-filled in the grid — Easy gives you more starting letters so fewer deductions are needed, while Hard leaves the grid almost empty, requiring you to work out the placement of nearly every letter yourself.

A Daily Puzzle, Streaks and Unlimited Practice

Every day there is one numbered puzzle — Puzaku #N — the same for everyone. Monday's is gentle and the week gets harder towards Saturday; Sunday is a 9×9 Sunday Special. Only your first attempt counts, and solving the daily puzzle day after day builds your streak.

Practice is unlimited: each level uses a different common word, your progress is saved in your browser, and later levels get harder by giving you fewer starting letters. Hints are simple — each one adds a fixed time to your clock (30 seconds, or 60 on Hard), so a clean solve always wins.

The leaderboard ranks each day's first attempts — solves with no hints first, then by time — and tells you what share of that day's solvers you finished ahead of. A monthly points league adds up your daily results (Sunday counts double), and a Streaks board shows who has solved the most days in a row.

Cloud Save and Leaderboard

By default, all your progress is stored locally in your browser. If you want to protect your stats or compete on the leaderboard, you can optionally enable cloud save in the settings. This syncs your progress to a secure cloud database so you can restore it on any new device using a unique Save Code. No account, email, or personal details are required — Puzaku generates an anonymous player ID automatically.

The leaderboard is double opt-in: you must enable cloud save first, then separately choose to show your times publicly. Your leaderboard name is a randomly generated three-word phrase like "Glacial Iron Wolverine" — anonymous, consistent, and unique to you. You can remove yourself from the leaderboard at any time with a single tap.
